A deflection yoke is a kind of magnetic lens, used in cathode ray tubes to scan the electron beam both vertically and horizontally over the whole screen. In a CRT television, the electron beam is moved in a raster scan on the screen.

1999年3月19日 · This paper describes the development of designing the deflection yoke (DY) of CRT from the standpoint of the historical view. It relates the introduction of field parameters, the deflection aberration theory, weight function, Trilemma, the birth of self-convergence color picture tube, multipole field correction theory, the calculation and ...

The evolution of the magnetic deflection yoke to wide angles and high performance, and the modification of cathode-ray-tube (CRT) structures has responded to ever-more-demanding performance in diverse applications. This article probes the past to extract those basics by which precise deflection performance of CRT systems may be calculated.

A high quality deflection yoke (DY) is one of the most important factors for a high quality monitor. The role of the deflection yoke is to deflect electron beams in horizontal and vertical directions. If the magnetic field is formed incorrectly, misconvergence of beams may occur resulting in blurred image on the screen of the monitor.

lead to the increase of deflection current and the rise in temperature of deflection yoke (DY). It is an efficient method to use a slot core for the increase of the deflection sensitivity. In this paper, the deflection sensitivity is defined as the proportion of the deflection angle to the coil cur­ rent.

2022年7月25日 · Looking at a typical raster CRT deflection yoke, there appear to be two very different pairs of coils. There is the pair on the inside that curves outwards, and the pair on the outside, which are wound around a ferrite core. The inside coil is the horizontal deflection coil, which seems to make sense.

A deflection yoke is a component in a television display that generates signals to move the electron beam across and down the screen to create the raster pattern on a cathode ray tube. From: BKSTS Illustrated Dictionary of Moving Image Technology [2013]

In this paper, we introduce an efficient three-dimensional magnetic field mapping system for a Deflection Yoke (DY) in Cathode-Ray Tube (CRT). A three-axis Hall probe mounted in a small cylindrical bar and three-stepping motors placed in a non …

Find out information about deflection yoke. An assembly of one or more electromagnets that is placed around the neck of an electron-beam tube to produce a magnetic field for deflection of one or more...

deflection yoke (DY) is an important part ofa CRT. On the one hand, it is an electron opties element. The deflection field makes the electron beam scanning the whote screen. It relates the curvature of screen and mask, the correction lens as well as the curves of the glass neck and cone. We can also understand this point frem a kind of picture ...
